92 indicates a conductor connected to conductor 82, at a pointintermediate its length, and leading to one terminal of push-button 77,and 93 indicates a conductor connected to conductor 79, at a pointintermediate its length, and leading to the other terminal of thepushbutton.

Supposing that it is desired that the signal be sounded or made at sevena. 111., twelve 111., and one and six p. 111., all except four of thecontact-points 10 are bent outward, as shown in Fig. 3, so that theirends lie out of reach of terminal 11, the four points which are not sobentbeing those which lie opposite terminal 11 at the hours indicated.Starting with the clock at 6.55 a. 1n., as shown, the operation is asfollows: lVhen the clock has advanced so as to indicate seven a. 111.,the hourhand, terminals 10, and gear 8 moving forward together, acurrent is sent from the standard clock (not shown) through the coil ofmagnet 13. The magnet, when thus energized, draws arm 12 up to theposition indi cated in dotted lines, terminal 11 is thereby thrown downto the position indicated and comes into contact with one of the points10. Then the magnet 13 is energized at hours other than those namedabove, terminal 11 is thrown down, but fails to make contact with one ofthe points 10 owing to the fact that those particular points have beenbent out of the way, as described above. At the instant that contact ismade between one of points 10 and terminal 11 the following circuit iscompleted: from the battery through conductor 84, terminal 5(), disk 45,frame 26, conductors 80, conductors 79, terminal 11, contactpoint-10,frame 6, shaft 14, one of segments 17, terminal 20, conductor 82, thecoil of magnet 72, conductor 83, pivot 70 and hook 69, lever 63, andconductor 85 back to the battery. The completion of this circuitenergizes magnet 7 2'and causes hook 69 to be drawn away from the end oflever 63. Lever 63 is thereby freed, and, on account of the action ofspring 65, flies upward and comes into contact with terminal 66, thismovement of lever 63 at the same time breaking the circuit describedabove, depriving magnet 72 of its power and IIO allowing hook 69 to bedrawn back into place by spring 74. When lever 63 comes into contactwith terminal 66, a circuit is completed through the motor through thefollowing parts: from the battery through conductor 84, terminal 50,disk 45, frame 26, conductor 80, cut-out 7S, conductor 81, terminals 58,terminals 61, conductor 89 to one terminal of the motor-armature, fromthe other terminal of the motor-armature through conductor 88, terminals62, terminals 59, conductor 90, through the field-coil of the motor,conductor 91, terminal 66, lever 63, and conductor 85 back to thebattery. The completion of this circuit through themotor causes it torevolve in the proper direction to cause cord 23 to be wound upon drum22. The winding up of cord 23 upon drum 22 causes arm 24 of the signaldevice to be drawn down and the signal is thus sounded and continuesuntil arm 24 is released in a manner to be explained. Cord 55 beingsecured to cord 23 advances with it, thus drawing down arm 52 againstthe action of spring 53. Pin 54 of said arm engages the outer portion ofarm 36 and causes said arm to move downward to the position indicated indotted lines in Fig. 2, pin 54 slipping from the end of arm 36 when thisposition is reached. The downward movement of arm 36 winds up spring 33.Spring 33 then causes gear 32 to move in the direction indicated by thearrow thereon, said motion continuing until arm 34 comes into contactwith stop 35. The forward movement of gear 32 is regulated andcontrolled by means of escapement-wheel 40, pallet 41, and pendulum 4243, and said movement of gear 32, through gear 44, causes disk 45 andcam 47 to move in the direction indicated by the arrow thereon. wardmovement of cam 47 continues, said camv comes into contact with arm 57,cansing said arm to swing upon its pivot. This movement of arm 57 firstcauses the 1notorcircuit to be broken, terminals 58 61 and 59 62 beingseparated, and the motor is therefore stopped, and then a new circuit isestablished as follows: from the battery through conductor 84, terminal50, disk 45, frame 26, conductor 80, cut-out 78, conductor 81, terminals58 and 60, conductor 88, through the motor-armature, conductor 89,terminals 61, terminals 59, conductor 90, through the fieldmagnet of themotor, conductor 91, terminal 66, lever 63, and conductor 85 back to thebattery, thus reversing the motor and cansing cords 23 and to be unwoundfrom drum 22, arm 52 returning to its original position and the signalbeing released. Pin 54 is enabled to pass the end of arm 36, owing tothe arrangement of slot 38 in said arm and pin 37 in shaft 27, as isclearly apparent from Fig. 2. During the entire movement of the motor,both in the forward and in the back ward direction, disk 45 and cam 47are constantly advancing, and when notch 46 of disk 45 reaches a pointopposite the free end of As the for-' terminal 50 the said end of saidterminal springs down into the notch and thus c0111- pletes thefollowing circuit by bringing terminals 50 and 51 together: from thebattery through conductor 84, terminals 50, terminals 51, conductor 87,through the coils of magnets 68, conductors S6 and 85, back to thebattery. The completion of the above-mentioned circuit causes themagnets 68 to be energized, these in turn drawing down armature 67, thusbreaking the contact between lever 63 and terminal 66, and thus stoppingthe motor, and this movement brings the free end of lever 63 intoengagement with hook 69. As disk 45 continues to advance, notch 46 ismoved away from the free end of terminal 56 and said free end is forcedout upon the periphery of the disk, thus breaking the contact betweenterminals 50 and 51. Disk 45 and cam 47 continue to advance until arm 34comes into contact with stop 35, cam 47 at the same time reaching aposition which will allow arm 57 to return to the position shown in Fig.2. The entire apparatus is then in its original position and is ready tobe again operated in the manner described above.

(Jam 47 is made adjustable in order to regulate the reversing mechanismof the motor.

The time consumed in one revolution of disk 45, and the consequentlength of signal, is regulated by pendulum 42 43.

\Vhen the clock has advanced to a position indicating about 6.30 p.111., pin 9 has reached a position where it will engage one of the teethof wheel 16, and a further advance of the hour-shaft causes said wheelto be advanced one division, the movement of said wheel causing asimilar movement of wheel 15, thus bringing one of the non-conductingsegments 18 opposite terminal 20. The mechanism shown in Fig. 2therefore remains in.- operative during the night, owing to the factthat no ciurent can pass through the coil of magnet 7 2. At 6.30 a. 1n.pin 9 again causes wheels 16 and 15 to advance one segment, thusbringing terminal 20 into engagement with one of the conducting-segments17,unless the day happens to be Sunday, a non-conduetin g segment beingintroduced for the daytime of Sunday. Out-out 78 is provided so that themechanism may be made inoperative upon any days on which the factory isnot running, and button 77 is provided so that if it is desired tooperate the signal at some unusual hour it may be done.
